Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a special casting mold for aluminum rod alloy composition testing samples. Background Technology

[0002] Aluminum alloy casting is a process in which prepared aluminum alloy casting materials are fed into a mold and allowed to solidify, resulting in a product that resembles the mold cavity.

[0003] Traditional casting molds used in the production of aluminum rod alloys lack a rapid heat dissipation structure, which makes the entire mold take a long time to cool and form, reducing the production efficiency of test samples. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A special casting mold for aluminum rod alloy composition testing samples includes:

[0006] The mold body has a forming cavity, and multiple sets of flow channels are formed on the mold body and around the forming cavity. A connecting pipe communicating with the flow channels is integrally formed at the bottom of the mold body.

[0007] A conveying assembly includes a connecting pipe and a fixed cylinder arranged sequentially from top to bottom. A water inlet pipe is connected to the side wall of the fixed cylinder. The connecting pipe is movably sleeved on the surface of the connecting pipe. An elastic moving member is slidably connected inside the connecting pipe. The elastic moving member has a through hole. When the connecting pipe is sleeved on the surface of the connecting pipe, the bottom of the connecting pipe moves downward in contact with the elastic moving member, and the through hole opens, allowing the cooling liquid in the fixed cylinder to enter the connecting pipe through the through hole.

[0008] As an improvement to the above technical solution, the elastic moving component includes a movable sleeve that is slidably disposed inside the connecting pipe, a through hole that is opened on the movable sleeve, a spring that is fixedly installed between the top of the inner wall of the connecting pipe and the movable sleeve, and an opening that allows the movable sleeve cavity to communicate with the connecting pipe.

[0009] As an improvement to the above technical solution, branch pipes are provided in the flow channel, and a main pipe is provided at the bottom of the multiple sets of branch pipes, with the main pipe extending into the connecting pipe.

[0010] As an improvement to the above technical solution, a water outlet pipe is rotatably inserted into the bottom of the fixed cylinder, the top of the water outlet pipe passes through the movable sleeve and extends to the outside of the movable sleeve, one end of the water outlet pipe extending to the outside of the movable sleeve is threadedly connected to the bottom of the main pipe, and the water outlet pipe is slidably connected to the movable sleeve.

[0011] As an improvement to the above technical solution, the molding cavity has a conical structure.

[0012] The beneficial effects of this utility model are:

[0013] The cooling liquid delivery is controlled by an elastic moving component. Before casting is complete, the through-hole is closed to prevent cooling liquid from entering the mold when not needed. When cooling is required, the elastic moving component moves down to open the through-hole by connecting the connecting pipe, initiating the cooling process. After cooling is complete, the connecting pipe is removed, the elastic moving component returns to its original position, closing the through-hole and stopping the cooling liquid delivery. This allows for flexible adjustment of the cooling process according to the actual cooling needs of the sample, effectively reducing defects such as internal stress, deformation, or cracking caused by improper cooling, and improving the quality and stability of the sample.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] A special casting mold for aluminum rod alloy composition testing samples includes:

[0020] The mold body 10 has a molding cavity 11 and multiple sets of flow channels 12 are formed on the mold body 10 and around the molding cavity 11. The bottom of the mold body is integrally formed with a connecting pipe 15 that communicates with the flow channels 12.

[0021] The conveying assembly 20 includes a connecting pipe 22 and a fixed cylinder 21 connected sequentially from top to bottom. A water inlet pipe 26 is connected to the side wall of the fixed cylinder 21. The connecting pipe 22 is movably sleeved on the surface of the connecting pipe 15. An elastic moving member is slidably connected inside the connecting pipe 22. A through hole 23 is opened on the elastic moving member. When the connecting pipe 22 is sleeved on the surface of the connecting pipe 15, the bottom of the connecting pipe 15 moves downward in contact with the elastic moving member, and the through hole 23 opens. The cooling liquid in the fixed cylinder 21 enters the connecting pipe 15 through the through hole 23.

[0022] Specifically, during the casting operation, molten aluminum alloy is injected into the forming cavity 11 of the mold body 10. The molten metal gradually fills the forming cavity 11. After casting is completed, cooling liquid can be injected into the fixed cylinder 21 through the water inlet pipe 26. At this time, the elastic moving part in the connecting pipe 22 is in its initial position, and the through hole 23 on it is in the closed state. (Refer to...) Figure 2 Cooling liquid cannot enter the connecting pipe 15. When cooling of the sample in the molding cavity 11 is required, the connecting pipe 22 is movably sleeved onto the surface of the connecting pipe 15. As the connecting pipe 22 and the connecting pipe 15 are sleeved deeper, the bottom of the connecting pipe 15 will abut against the elastic moving member, causing the elastic moving member to move downward. After the elastic moving member moves downward, the through hole enters the fixed cylinder 21, and the through hole 23 opens. (Reference) Figure 3 After the through hole 23 is opened, the cooling liquid in the fixed cylinder 21 will enter the connecting pipe 15 through the through hole 23. Since the connecting pipe 15 is connected to the flow channel 12 on the mold body 10, the cooling liquid can further flow into the flow channel 12. When the cooling liquid flows in the flow channel 12, it will absorb the heat of the sample in the molding cavity, thereby cooling the sample and accelerating the solidification and molding process of the sample. When the sample is cooled to a suitable degree, the connecting pipe 22 is removed from the connecting pipe 15. At this time, the elastic moving part will return to its initial position under its own elasticity. The through hole 23 enters the connecting pipe 22. The through hole 23 is closed to stop the delivery of cooling liquid. After that, the molded aluminum rod alloy composition test sample can be taken out from the molding cavity of the mold body for subsequent testing and other operations.

[0023] In one embodiment, the elastic moving member includes a movable sleeve 27 slidably disposed within the connecting pipe 22, a through hole 23 formed on the movable sleeve 27, and a spring 24 fixedly installed between the top of the inner wall of the connecting pipe 22 and the movable sleeve 27. The top of the movable sleeve 27 has an opening for the cavity of the movable sleeve 27 to communicate with the connecting pipe 15. When the connecting pipe 22 is not sleeved with the connecting pipe 15, the movable sleeve 27 is inside the connecting pipe 22 under the elastic force of the spring 24, and the through hole 23 is blocked and sealed by the inner wall of the connecting pipe 22, and is in a closed state, so that the cooling liquid cannot enter the connecting pipe 15. When the bottom of the connecting pipe 15 contacts the top of the movable sleeve 27 and applies pressure, the movable sleeve 27 slides downward against the elastic force of the spring 24. As the movable sleeve 27 moves downward, the through hole 23 gradually moves into the fixed cylinder 21 and opens. The cooling liquid in the fixed cylinder 21 enters the movable sleeve 27 through the through hole 23, and then enters the connecting pipe 15 through the opening.

[0024] In one embodiment, branch pipes 13 are provided within the flow channel 12, and a main pipe 14 is provided at the bottom of multiple sets of branch pipes 13. The main pipe 14 extends into the connecting pipe 15. A water outlet pipe 25 is rotatably inserted into the bottom of the fixed cylinder 21. The top of the water outlet pipe 25 passes through the movable sleeve 27 and extends to the outside of the movable sleeve 27. One end of the water outlet pipe 25 extending to the outside of the movable sleeve 27 is threadedly connected to the bottom of the main pipe 14. The water outlet pipe 25 is slidably connected to the movable sleeve 27, and the connecting pipe 22 is sleeved onto the connecting pipe. 15. At the same time, the outlet pipe 25 is inserted into the main pipe 14. Rotating the outlet pipe 25 causes the connecting pipe 22 to move upward through the fixed cylinder 21. By controlling the upward movement distance of the connecting pipe 22, the opening size of the through hole 23 on the moving sleeve 27 can be adjusted, thereby controlling the flow rate of the coolant entering the connecting pipe 15 and the flow channel 12. After entering the flow channel 12, the coolant fills the flow channel 12 and enters the branch pipe 13. Finally, it converges into the main pipe 14 and is transported by the main pipe 14 to the outlet pipe 25, from which it flows out.

[0025] In one embodiment, the molding cavity 11 has a conical structure, which makes it relatively convenient to remove the molded sample, reduces the friction between the sample and the inner wall of the mold, and facilitates demolding.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
